Claims.

`My invention relates to shade securing means. In certain types ofreectors it has heretofore been the practice to provide each reflectorwith means permanently secured thereto for attaching the reiiector inposition with respect to a lamp socket. As there are various types oflamp sockets, different forms of attaching means had to be provided forthese reflectors in order to adapt them for the different types ofsockets. As the attaching means were permanently secured to thereflectors, this necessitated that the distributor 01' dealer carry aline of reiiectors for each type of socket.

One of the objects of my invention is to provide a reflector supportingattachment which can be readily attached and detached with respect tothe reflector so that by having a suitable supply of various types ofthese attachments on hand the dealer or distributor can t up a singleliney of reflectors for use with any of the various types of sockets,thus enabling him to carry but a single line of reflectors, whereheretoforeit had been necessary for him to carry a number of lines, onefor each type of socket.

A further object is to provide such a construction in which asubstantial portion of the reflector supporting attachment is locatedinside the neck of the reector.

A still further object is to provide such a construction which will bedurable and efficient in use and inexpensive to manufacture.

Further objects will appear from the description and the appendedclaims.

In the drawings in which three forms of the invention are shown:

Figure 1 is a fragmentary side elevational view showing a reflectorsecured in position with respect to a porcelain socket;

Fig. 2 is a plan view of the attachment;

Fig. 3 is a section on line 3 3 of Fig. 2;

Fig. 4 is a perspective of one of the securing springs;

Fig. 5 is a side elevational View showing another form of attachment;

Fig. 6 is a plan view of the attachment of Fig. 5;

Fig. 7 is a section on line 7--7 of Fig. 6;

Fig. 8 is a side elevational View cf another form of attachment;

Fig. 9 is an axial section through the attachment of Fig. 8; and

Fig. 10 is a section on line 10-10 of Fig. 9.

Referring to the drawings in detail and rst to Figs. 1 to 4, inclusive,the construction shown therein comprises a porcelain socket 1 having an(Cl. 24U-128) outwardly extending annular flange 2y at its lower end, areector 3 having an inwardly extending annular flange 4 at its upper endand a reflector supporting member 5 having a snap connection t with theinwardly extending 4flange 4 of-theL re- 60 flector and having aclamping connection with the porcelain socket. i The snap connectioncomprises a pairA of duplex leaf spring members 7 and 8 riveted'at- 9 tothe inside of the annular collar ld'which can r65 be inserted downthrough the opening in the annular flange 4 of the reflector. Thisannular collar 10 is provided with four aperturesv ,1-1, one for eachend of each of the duplex springs 5, thus enabling these latch-like endsto extend `through 7o the openings into latching engagement with theunderside of thereectorflange 4. Theselatching ends are beveled offas'indicated in Figs. 1, 3, and 4, to facilitate their entry into theopen ing in the reiiector flangethe slope being such that the latchedends are forced inwardly as the collar is inserted into the fiangeopening, the latch members snapping out as soon' as their upper edgeshave'passed underneath the reflector flange. y, t 80 The distance towhich the collar 10 can 'bef inserted into the ange opening'is limitedby the engagement of the downwardly bumped portions 12 of the outwardlyextending flange 13 `at, the upper end of the collar which-engage theupper face of the inwardly extending flange of the reflector. Thesedownwardly bumped projections 12 provide a slightly yielding engagementwith the ange of the reflector, the flange being en-w gaged on its lowerside by the four spring latch4` 90 members 5 and being engaged on theupper surface by the downwardly bumped projections 12 of the collarange.

The clamp for securing the attachment to theirc socket comprises a pairof clamping members 14` 95 riveted to the upwardly projecting ears 15 onthe collar member 10 and having straps 16 punched inwardly forengagement above the annular supporting flange 2 on the socket. A pairynof clamping screws 17 are provided for drawing 100 the ends of theclamping members toward each other to bring the straps rmly intoengagement with the sides of the socket. In order to hold the attachmentin proper relation with respect tom the refiector and prevent relativerotation there-L between, portions 18 of the outwardly extending flangeare cut and struck downwardly so as to fit in suitably positionednotches 1,9 formed in the inwardly extending flange of the reector. Withthis construction, it will be seen that th' '-110 -14b on: the` reector.supportingattachment reflector supporting attachment can be readilyattached to the reflector so that the attachments and reectors can beshipped unassembled to the distributors and dealers who can then fit upthe reflectors as required with the desired type of socket attachingmember.

Figs. 5, 6,v and'? show a reectorattachment for another type/of: socketin' which 'portions of the socket of the interior construction are heldup by means of a threaded supporting ring '14a screwed inside of thethreaded skirt portionla of the socket casing. In this form, thereflector supporting collar 10 is formed as an integral @part of thescrew ring 14a which serves to support the socket interior. The collar.and spring latching construction is precisely the same as that shown inFigs. 1 to 4, inclusive. The screw ring 14a is provided with aninwardlyextendingflange at its upper end on which rests the shoulderfofvthe socket interior.
